Heat transfer to liquid metal: Review of data and correlations for tube bundles

Konstantin Mikityuk

Four sets of experimental data (total of 658 data points) for heat transfer to liquid metals (NaK of different compositions and Hg) flowing in a triangular or square lattice of cylindrical rods with pitch-to-diameter ratios of 1.1 up to 1.95 for a wide ran ...

Advanced surface derivatization of superparamagnetic iron oxide nanoparticles in a fixed bed magnetic reactor for bio-application

Jatuporn Salaklang

There is an enormous interest in exploiting nanoparticles in various biomedical applications since their size scale is similar to that of biological molecules (e.g., proteins, DNA) and structures (e.g., viruses and bacteria). As the field continues to deve ...
